Lgggfiggp Specification of Letters Patent.

Application filed November 20, 1919;

1 0 all whom it may concern:

Be it known that 1, J OHN REID, a subject of the King of Great Britain, and residing at 30 Church street, in the city of New York, in the State of New York, in the United States of America, have invented a new and useful Furnace-Front, of which the following is a specification.

The invention relates to furnace fronts as described in the present specification and illustrated in the accompanying drawings that form part of the same.

. The invention consists essentially of the novel construction and arrangement-of parts, whereby the various new features introduced contributeto the pro-per combustion of the fuel and to better facilities for installation and shipment.

The objects of the invention are to increase the steam generating properties of oil fuel furnaces and thereby save in the consumption of fuel and benefit by the efficiency gained; to facilitate the assembly of the parts and the adjustment of the air feed after assembly; to eliminate the expense, inconvenience, and delays incident to the repairs, which may be necessary in marine in stallations en route; to further develop the Reid type of furnace with a view to stand-- ardization and with a view to rapid and efficient installations and to effect improvements concerning directly or indirectly the following patented inventions and applications pending: Numbers 1,318,331, October 7th, 1919, 1,297,247, March 11th, 1919, Serial Nos. 317,537, filed August 14th, 1919, 317,538, I

Fig. 7 is a longitudinal sectional detail of the main cone deflector.

Fig. 8 is a longitudinal sectional view of the assembled air cylinder and regulating sleeve. I

Fig. 9 is an elevation of the back plate, showing another arrangement of the intermediate parts.

Fig. 10 is a vertical sectional view of the front as illustrated in Fig. 8 without the valve gear.

Fig. 11 is a detail, showing a simple form of rod control for the main and the inner cone deflectors.

Fig. 12 is an elevation of the back plate, showing the intermediate parts in an oil burning assembly Without valves other than the regulating sleeve.

Fig. 13 is an elevation of the back plate, showing a rotatable regulating sleeve taking the place of all other valves and operated in register in its three cooperating parts, the

air cylinder 1, the regulating sleeve 2, and the cone deflector 3, though the general make up'of the furnace-front materially contributes to its efficien-cy.

The air cylinder 1 is a tubular piece of metal having a flange a at the inner end and an annular row of air ports 5 adjacent to said flange. The sleeve 2 fits over the cylinder 1 andis adjusted to regulate the size of the ports 5.

The cone deflector 3 slides into the air cylinder 1 and the radial vanes 6 extending from the rim 7 through to the small end 8 of the cone project in a radial direction to the interior wall of the cylinder and thereby divide the inrushing air, so that it reaches the brink of the cone end in separated streams and shoots over the edge in the direction of the spreading oil spray.

The cone shell 3 is outwardly in the shape of the frustum of a cone, which results in a bell like casing for the passage of the oil P 9 9 c ntrallythere hrough, the nozzle 10 being at the inner extremity slightly beyond the inner and small end of the cone deflector in inner cone deflecting plate 11 is mounted on the pipe 9 in an inverted position. in relation to the setting of the cone deflector 3 and adjacent to the outlet end 8 of the latter. I

It will be thus seen that the air in a forced draft or other system is directed into the combustion chamber in many distinct paths andby two main roads, the outside and the inside, the outside road being subdivided into the many inclined paths, separated by the vanes (5, into which the air flows either beyond the outer or inner ends of the sleeve 2, therefore at the beginning or toward the ends of the inclined paths, in the latter ase through the ports 5. The inside road is through the cone shell or bell like casing and the a'r in this case flows behind the rim 7 and is deflected by the minor cone deflector 11 from which in Figs. 4 to 10 it strikes the inner wall of tie cone deflector 3 and is emitted from the outlet 3 to the burning oil gas, and in Figs. 1 to 3 is emitted to the flame between the minor cone 12 and the adiustable collar 13 and the minor cone 12 in tnis form of the invention is supported by the blades 14 separating a plurality of passages. The minor cone 12 guides the flow of so that it follows the spread of the flame from the nozzle and saves undue force of air at the nozzle outlet, the same remarks applying equally to the minor cone 11. u

The structure shown in Figs. 1 and 2 is very well suited to the oil burning air register already described and in this form of front the back plate 15 is shown as having permanently a rear half 10 of an air deiilectii v7 batlle plate above the air register in the term of an arch, the front half 17 extendi re 1 ardly from the front plate 19, both front and back plates haying openings for the installation of the air burning eqi'sipineiubs, as for example the air cylinder is inserted from the rear side of the back plate 15 and the flange 4- rigidlv secured to the latter. The regulating sleeve 2 is mounted on. the cylinder 1 from the opening in the front plate 18 and similarly the defleeting cone 3 is inserted in the cylinder 1 and slidably arranged so as to increase or decrease its distance from the closure plate 19, that supports the pipe 9 within the inwardly projecting flange 20 supporting the sleeve 21, on which the collar 13 is adjustably mounted.

The closure plate 19 is rigidly secured and the regulating sleeve 2 and adjustable collar 13 are set, so as to obtain the best results in regard to the proper combustion of the oil.

Tn 12 thesleeve 2 and collar 13 are shown as adjusted by rods, 22 and 23 extends ing through the front plate and by such an arrangement an engineer can regulate h1s fires according to existing conditions regarding the quality and the quantity of oil feed and the force of the air draft.

The flare in front and rear halves 2&1 and 25 separates the front and back plates at the lower half portion and is in the form of an arc-shaped intermediate wall flanged at its upper ends 2 which at their angle form seats for the side valves 27, the other 28 being at the lower ends of the baffle wall formed by the extensions 16 and 17.

The packing 29 is introduced between the meeting ends of the baffle and flare walls, so that an air pocket is formed between the front and back plates and the only opening thereinto is by a lower door 30, which may be used for natural draft and which corresponds to the ash pit door in a coal burning front.

The operating means for the side valves is not shown in Figs. 1 and 2, as it is obvious that they may be turned by a handle on the end of a shaft projecting through the front plate and illustrated in many of the afore said pending applications.

The brick work 31 is built up in a suitable way to accomplish the best results.

The form of the invention as in Figs. 1 and 2 is for an oil burning furnace only though a slight modification of the frame will make it readily convertible to a front suitable for a coal burning furnace.

Tu Figs. 12, 13. 141, and 15, the invention is shown for oil burning furnaces only, gh it may be of the converti le type, as only neces itates a change in the frame. 1e four figures mentioned above, the ,late 92 and back plate 93 and interbatle plate and flare9 l are -'-'eml,-.ed in any suitable manner or cast as one piece if desired to form the main frame.

The plate 94: turns downuuirdly at each end above the air register formed of the air cylinder 95 having the ports 96 and receiving the cone-deflector 97. In Figs. 12 and 18 the sleeve 98 is similar to the regulating sleeves aforesaid, but takes the place of other valves entirely and is operated by the screw rods 99 turned by the handle 100, and screwing in the turn-buckles 101, which are secured to the sleeeve 98.

In Figs. 13 and 15 the air cylinder extends little further toward the front plate and the sleeve 102 rotates on said cylinder and uncovers ports in the cylinder and brings them into registry with the ports 103 in the sleeve.

The rack 10% is mounted on the sleeve 102 and this coacts in turning the sleeve with the gear wheel 105, which is mounted on the shaft 106 and turned by the handle 107. 1n this way all other valves are dispensed with and the air is admitted to through the cone deflector and air cylinder according to the openings disclosed in the operation of the regulating sleeve.

In operation the air flows in preferably from an individual heater in a forced draft system, as it will then be more even as to quantity and force. The air entering the front between the plates first strikes the top baffle. This baffle distributes it, so that it flows down each side and upwardly and enters the air register between the rim of the same and the closure plate and reaches the interior and flows therethrough coming into contact with the minor. cone deflector, which guides the flow toward the spreading flame. The greatest flow of air passes between the vanes and through the ports in the air cylinder and this flows on to the spreading cone of flame and thus promotes combustion. The optional features regarding frame and valve construction and the shapes of the air pockets, well as the use of these parts in converting a coal front to an oil front must be particularly emphasized herein, because the removable and adjustable parts bid fair to make complete new fronts out of the several different arrangements of valves, the elimination of valves and the construction of the frame.

It has been explained herein that many forms'of the invention may be used and it must further be understood that without departing from the spirit of the invention, any changes within the scope of the claims following will be included in the protection accorded.
